INVENTOR BY M p WITNESS: I ATTORNEY Patented Oct. 9, 1923.

UNITED STATES I THOMAS M. ABRAHAM, OF MANQU IN, VIRGINIA.

ACCELERATOR.

Application filed July 12, 1922. Serial No. 574,483.

To all whom it may concern:

Be it known that I, THOMAS M. ABRAHAM, a citizen of the United States,residing at Manquin, in the county of King WVilliarn and State ofVirginia, have invented new and useful Improvements in Accelerators, of

which the following is'a specification.

My present invention has reference toa foot throttle for a well-knownsmall type of automobiles.

My object is to produce a device of this character which shall be of anextremely simple construction, cheaply manufactured, easily appliedwithout removing any of the parts of the automobile, which will notinterfere with the hand throttle, and which will be thoroughly efiicientin operation.

Other objects will present themselves as the nature of the constructionis better understood, reference being had to the drawings whichaccompany and which form part of this application.

In the drawings Figure 1 is a side elevation of a sufficient portion ofan automobile to illustrate the application of the improvement, partsbeing in section.

Figure 2 is a similar top plan view.

Figure 3 is a sectional view on the line 3-3 of Figure 2, the outline ofthe engine being shown diagrammatically.

Figure 4 is a perspective view of the plate or bracket and the rodsassociated therewith.

In the drawings a suflicient portion of the front of an automobile towhich the improvement is attached, has been illustrated as has also asufficient portion of the engine. In carrying out my invention I securean angle bracket 1 by one of the screws 2 that connect the waterconducting hose. To the horizontal lower branch of the bracket 1, Ipivot as at 3 an angle lever 41. To one of the arms of the bell cranklever a I attach a spring 5, whose opposite end is suitably supported.as shown in the drawings.

The carbureter for the motor 8 is indicated by the numeral 9. Thecarbureter is of the usual construction, the butterfly or throttle valvethereof having a stem projecting through a suitable opening in the topof the carbureter casing and being provided with the usual angle arm 10.1

Both arms of the bell crank lever are provided with openings, and thereis passed through the opening of the arm provided with the spring 5 theangle end of the foot or throttle lever 11. As a matter of fact thethrottle lever has its angle end passing through openings in an anglebracket plate 12, the said angle end of the arm being previded with anopening through which is' passed a cotter pin 13. The throttle leverpasses through an opening in the dash 6 of the automobile 7 close to thefloor board,

the inner end of the said rod being provided with a suitable head 14. I

The opening in the second arm of the bell crank lever receivestherethrough the angle end 15 of a rod 16. The end 16 is provided withan opening through which is passed a cotter pin. Both ends of. the rod16 are arranged at angles, being similarly directed, and the outer angleend passes through the usual opening I in the valve lever 10, a cotterpin 17 sustaining the said end of the rod in the said opening. The rod16 passes through an opening in the upwardly directed or angle end 18 ofa plate 19. The plate has an opening adjacent to its outer end, andthrough this opening the angle outer end of the rod 16 passes. The angleend 18 of the plate 19 is provided with a rounded opening through whichpasses a rod 20. The rod 20 has its end provided with a plurality ofapertures 21 through any one of which there is passed a stop member inthe nature of a cotter pin 22. The opposite end of the rod 20 isconnected, as at 23 to the angle end 2% of the hand operatedthrottlerodi25.

It will be apparent that by providing the angle plate 19 a pressure maybe exerted by the foot throttle rod 11 for influencing the hand throttlerod 20, the latter passing freely through the opening in the angle end18 of the plate or bracket 19. Because of the spring 5 the bell cranklever 12 influences the rod 16 to hold the valve of the carbureter 9open'to a position determined by the hand throttle lever, and also thehand throttle lever may be operated to move the rod 20 through theopening permitting the spring to further influence the rod 16, and thusfurther open the valve of the carbu reter. The movement of the lever ina reverse direction will, of course, cause the cotter pin 22 to contactwith the angle end 18 of the plate or bracket 19 to move the handle orlever 20 of the valve of the carbureter in an opposite direction andagainst the pressure of the spring 5.

Having described the invention, I claim 1. In combination with anautomobile having a hand operated throttle rod, of a foot throttlebetween the automobile and the carbureter for the motor thereof,including a bell crank lever having one of its arms spring influenced, athrottle rod between the body of the machine'and the said arm of thebell crank lever, a second rod connected to the second arm of the bellcrank lever and to the handle for'the throttle valve of the carbureter,a plate having an angle end connected to said rod, a rod passing freelythrough the angle end of the plate and pivotally connected to the handthrottle rod,a1'1d adjustable stop means between the angle end of theplate and the last mentioned rod.

2. The combination with an automobile having a hand operated rod, and amotor for said machine, of accelerating means between the motor and thebody of the automobile, including a removably supported bell cranklever, a spring connected to one of the arms of the bell crank lever andt0 the automobile, and the arms of the bell crank lever being apertured,a foot throttle rod leading from the automobile having an angle endreceived through one of the open ings in the bell crank lever, an anglebracket for the motor of the automobile, means sustaining the ends ofthe last mentioned rod so connected, an angle plate receiving the lastmentioned rod freely therethrough and connected to the said rod, and arod freely passing through the angle plate connected to the handoperated throttle rod and having its end projecting through the angleplate provided with spaced apertures, and a stop element passing throughone of said apertures. i

In testimony whereof I afiiX my signature.

THOMAS M. ABRAHAM.
